🛈⏬Modern day encryption is performed in two different ways. Check out http://YouTube.com/ITFreeTraining or http://itfreetraining.com for more of our always free training videos. Using the same key or using a pair of keys called the public and private keys. This video looks at how these systems work and how they can be used together to perform encryption. Download the PDF handout http://itfreetraining.com/Handouts/Ce... Encryption Types Encryption is the process of scrambling data so it cannot be read without a decryption key. Encryption prevents data being read by a 3rd party if it is intercepted by a 3rd party. The two encryption methods that are used today are symmetric and public key encryption. Symmetric Key Symmetric key encryption uses the same key to encrypt data as decrypt data. This is generally quite fast when compared with public key encryption. In order to protect the data, the key needs to be secured. If a 3rd party was able to gain access to the key, they could decrypt any data that was encrypt with that data. For this reason, a secure channel is required to transfer the key if you need to transfer data between two points. For example, if you encrypted data on a CD and mail it to another party, the key must also be transferred to the second party so that they can decrypt the data. This is often done using e-mail or the telephone. In a lot of cases, sending the data using one method and the key using another method is enough to protect the data as an attacker would need to get both in order to decrypt the data. Public Key Encryption This method of encryption uses two keys. One key is used to encrypt data and the other key is used to decrypt data. The advantage of this is that the public key can be downloaded by anyone. Anyone with the public key can encrypt data that can only be decrypted using a private key. This means the public key does not need to be secured. The private key does need to be keep in a safe place. The advantage of using such a system is the private key is not required by the other party to perform encryption. Since the private key does not need to be transferred to the second party there is no risk of the private key being intercepted by a 3rd party. Public Key encryption is slower when compared with symmetric key so it is not always suitable for every application. The math used is complex but to put it simply it uses the modulus or remainder operator. For example, if you wanted to solve X mod 5 = 2, the possible solutions would be 2, 7, 12 and so on. The private key provides additional information which allows the problem to be solved easily. The math is more complex and uses much larger numbers than this but basically public and private key encryption rely on the modulus operator to work. Combing The Two There are two reasons you want to combine the two. The first is that often communication will be broken into two steps. Key exchange and data exchange. For key exchange, to protect the key used in data exchange it is often encrypted using public key encryption. Although slower than symmetric key encryption, this method ensures the key cannot accessed by a 3rd party while being transferred. Since the key has been transferred using a secure channel, a symmetric key can be used for data exchange. In some cases, data exchange may be done using public key encryption. If this is the case, often the data exchange will be done using a small key size to reduce the processing time. The second reason that both may be used is when a symmetric key is used and the key needs to be provided to multiple users. For example, if you are using encryption file system (EFS) this allows multiple users to access the same file, which includes recovery users. In order to make this possible, multiple copies of the same key are stored in the file and protected from being read by encrypting it with the public key of each user that requires access.

What are certificates?
🛈⏬Certificates are used to prove identity and used for creating secure communication. Check out http://itfreetraining.com for more of our always free training videos. This video looks at how a certificate works, what is a certificate and how they are used for identification and secure communication. Download the PDF handout http://itfreetraining.com/Handouts/Certificates/WhatAreCertificates.pdf What is a certificate? A certificate is an electronic document that contains data fields. When compared to a traditional paper certificate there are some similarities between an electronic certificate and a physical certificate. Digital certificates like a physical certificate are issued by an authority. For example, a university may issue a certificate to a student to show that they have completed the necessary work in order to graduate. The next question is, would you trust a physically certificate? Digital certificates work the same way. They are issued from an authority and the question becomes would you trust the authority that issued the certificate? Electronic certificates also contain other fields like who or what the certificate was issued to, how long it is valid, the public key and the digital signature. If a digital certificate is presented to a user or computer, the user or computer is able to check the certificate to ensure the person using it should be using it. Also the certificate contains a digital signature which allows the certificate to be checked to make sure it has not been modified. Digital Signature A digital signature provides a method for a certificate to be checked to ensure it has not been modified. In order to do this, a hash value is created for the certificate. To generate a hash value the certificate is put through a function to create a single value. Hash functions are designed so different certificates will not produce the same value, however the hash value cannot be used to generate the original certificate. The same principal applies to a person's fingerprints. They can be used to identify a person, however using a finger print you could not work out the features of a person like what color hair they have. When a certificate is created, the hash value for that certificate is also created. Using a function involving the private key, a digital signature is created and added to the certificate. Digital Signature Example When a certificate is used, in order to check the certificate has not been changed, the following is done: The computer generates the hash value for the certificate. Next, the digital signature is put through a function using the public key which should result in the same hash value. If both values match, the certificate has not been modified. This prevents a 3rd party taking a certificate, changing the values in the certificate and using the certificate. Trust Model Certificates work off a trust model. An example of a trust model in computers is that a computer may have a sticker on it indicating which operating systems it will run. The consumer, seeing this sticker, must trust that the manufacture would not put this sticker on the laptop unless it will run that operating system. The customer must also trust the creator of that operating system would not allow a computer manufacturer to put a sticker on a computer that would not run that operating system. Certificate Trust Model Certificates are generally deployed in a hierarchy. At the top is the root certificate authority. This can be an internal Certificate Authority or an external authority like VeriSign. When an authority like VeriSign issues a certificate, they will perform a number of checks on the individual purchasing the certificate to ensure that they are a valid business. When a certificate is used it can be checked to see which authority issued that certificate. In order for the certificate to be used, the computer must trust the authority that it was issued from. Authorities like VeriSign are trusted by default on most operating systems. Certificate Error If a certificate is presented to the computer and it is not trusted, the computer will generate an error asking if the users want to trust the certificate. It is up to the user to decide if they believe the certificate is valid. Certificate Hierarchy Certificates use a hierarchy. At the top is the root CA, below these are subordinate CA's. Any level can issue certificates to subordinate CA's or direct to users, computers or devices. If the user, computer or device trusts the root CA, then any certificate that is issued by any CA in the hierarchy will automatically be trusted and thus used by the client.

Read more: http://spectrum.ieee.org/video/telecom/wireless/everything-you-need-to-know-about-5g Today’s mobile users want faster data speeds and more reliable service. The next generation of wireless networks—5G—promises to deliver that, and much more. With 5G, users should be able to download a high-definition film in under a second (a task that could take 10 minutes on 4G LTE). And wireless engineers say these networks will boost the development of other new technologies, too, such as autonomous vehicles, virtual reality, and the Internet of Things. If all goes well, telecommunications companies hope to debut the first commercial 5G networks in the early 2020s. Right now, though, 5G is still in the planning stages, and companies and industry groups are working together to figure out exactly what it will be. But they all agree on one matter: As the number of mobile users and their demand for data rises, 5G must handle far more traffic at much higher speeds than the base stations that make up today’s cellular networks.

🛈⏬If you read the news every now and then, you've probably heard of cookies on the internet. But what exactly is a cookie? When cookies were 'invented', they basically were little documents containing helpful information about you and your preferences. For instance, imagine selecting a certain language for a website you'd visit. You'd tell the website: Hey, I'd like to view your website in, say, English. The website would then save that information to a little document - a cookie on your computer. The next time you'd visit that website, it would be able to read the cookie it saved earlier. That way, the website could 'remember' your language and let you view the website in English, without you having to select your language again. Pretty handy, huh? But cookies are not limited to remembering just your language. In fact, a cookie can contain pretty much any kind of information. It can contain the time you visited a website or it can contain the items you added to your shopping basket. It can even contain all the links you clicked on a certain website, much like leaving a breadcrumb trail on the internet. A cookie can only contain so much text, but apart from it's size the possibilities are endless. What exactly is saved to a cookie, is up to the creator of the website you are visiting. Now, in contrary to the stuff a cookie can contain, there are limits to who can read your cookies. Imagine you first visit the website we talked about earlier, and you tell that website that your language is English. This is then saved to a cookie on your computer. If you'd visit a different website later, the latter wouldn't be able to read the cookie from the first website. In other words; only the same website that saves information to a cookie can access it. Since the beginning of cookies, the popularity of these clever little helpers exploded and they gradually evolved into a more complex, yet essential part of the internet. During their evolution, the amount of data cookies contained started to grow. At first they'd contain just a few preferences like your language and maybe your preferred layout for a website. But soon developers realized that the more information they could store about you, the better they could suit your needs. Cookies started containing more and more data, and eventually started pushing their size limitations. Subsequently, developers came up with a clever workaround. What if they would simply store a unique id in a cookie on your computer, and save the rest of the data in their own system? That way, they could save unlimited amounts of data. The cookie would simply serve as an identifier for your computer, much like a dog tag by which the website can recognize you and look up your data in it's own system. This was the first leap towards so called third party cookies. As mentioned, only the same website that saved data to a cookie can access it later. But one website can actually contain bits of another website. These bits and pieces of other websites, embedded in the website you're visiting, are actually able to access cookies they saved to your computer earlier. Imagine visiting a news website. Apart from news articles, many news websites contain a couple of ads. These ads are in most cases bits of other websites, embedded in to the news website. Now, the news website you're looking at may not have saved any cookies to your computer and thus know nothing about you. But where do the ads come from? It's not unlikely that the ads on the news website are embedded from the same website as the ads on another website you visited earlier. In fact, you may visit dozens of websites with ads which are all embedded from the same website. So what does this mean? This means that, if the website the ads come from has saved a cookie to your computer earlier, it can identify you - and save information about you -through other websites. So while you're reading that news website, shopping for new shoes, looking up cures for a headache or reading the latest gossip, the ads on those websites can identify you, look up your information in their own system and dynamically show ads that you're most likely to be interested in while simultaneously saving information about what you're doing online. So is this a bad thing? Are cookies dangerous? That depends, really. It is up to the creators of a website to determine what information they do and do not store, and more importantly; what they use that information for. Cookies are a tool. Just like a hammer, or a saw, they can be used for bad things, but they are intended to be used for good things. The responsibility lies with the people putting them to use. Cookies in a nutshell.

🛈⏬Difference between POP3 and IMAP What is IMAP and POP? These two are the most common incoming email protocols. These protocols are used to connect your mail box server to an email client. Here an email client refers to for an example (microsoft outlook or mozila thunderbird). So basically it allows you to send and receive the emails from mail client just we mentioned from Outlook or Thunderbird to your desktop/laptop. It also allows you to access your Emails through Online web services like Gmail, Microsoft Mail or on the mobile devices like your smart phones or tablets. Whats the difference? What is POP? So POP stands for Post office Protocol and the latest version is POP3 and it is supported by all email client and servers. POP3 download mails on your local device(Computer or Phone or Tablets) using the client and deletss them from the email server. By using POP an internet connected email client, accesses the mail server, then it download all your mails to local device(Computer or Phone or Tablets) and then it marks the messages for deletion on Email Server. So it means that if you have received emails using POP, they can only be accessible on specific email client on a specific device that you downloaded to. Which means that they can not be accessible through the other clients on devices other than that you downloaded to. However some email clients allow you to keep the copy of emails on server. and once you delete them from your client it may not get synced with the email server. What is IMAP? IMAP stands for Internet Message Access Protocol. Unlike POP3 which downloads and auto deletes the emails from email server, IMAP allows us to view emails from any internet connected Email Clients or web email services from any device at multiple locations. This feature has made it popular So basically if you are using IMAP to access your mails, your email client receives a copy of emails and the original stays on the email server, rather than deleting them from server. This feature makes is possible for us to access our mails from any client on any devices unless you deletes them from one client. Synchronization is done with all the devices and email server. If you delete an email from one of the client on one of the devices, it gets deleted from the server and other devices too. Main Differences are as below. 1) If you want to receive your e-mail messages only on one single computer or device, then POP3 is usefull, while using IMAP you can access your mails on multiple devices simultaneously at any time. 2) POP is a one way communication, because it deletes the messages once you download them to your local device and then disconnects the device from Mail Server, While IMAP is a two way communication, where retrives your mails and caches it on local device and keep the original content on server. Synchronication is done both the way. 3) Both protocols operate on different ports. 4) POP3 does not require an internet connection if you want to access the downloaded e-mails unless you want to retrieve new e-mails. While IMAP which stores your emails in cache only requires internet connection all the time.How DHCP works?
🛈⏬I will introduce DHCP - Dynamic Host Configuration Protocol. I will talk about what happens without this DHCP technology. How does it work step by step. What types of communications occur between DHCP clients and a DHCP server? How many steps are involved for a client to get necessary network credentials so that it could join a private network? What port numbers are used? Playlist: IPv4 basics - https://www.youtube.com/watch?v=vcArZIAmnYQ&list=PLSNNzog5eydt_plAtt3k_LYuIXrAS4aDZ This is my education channel.

🛈⏬Building Microservices with Spring Boot: http://www.informit.com/store/building-microservices-with-spring-boot-livelessons-9780134192451?WT.mc_id=Social_YT Use SSL/TLS and x509 Mutual Authentication is an excerpt from Building Microservices with Spring Boot - 6+ Hours of Video Instruction -- The term “microservices” has gained significant traction over the last few years. Describing a specific style of distributed software architecture, microservices are small, independently deployable units that work together to form a complete system. Microservices live on the web, live in the cloud, and work with all manner of data (SQL, NoSQL, In-Memory). They are production-ready services driven by ever-changing demands and scale. Java developers looking to adopt microservices need to consider the practical aspects of application development. How can services be developed quickly? How can a broad range of technologies be supported? How can a consistent programming model be kept? For many companies, the answer is Spring Boot and the wider Spring ecosystem. Description In this video training, Josh Long and Phil Webb demonstrate how and why Spring and Spring Boot offer the best way to build modern microservice systems. They look at the technologies and use-cases common to cloud-native microservice style applications as part of a larger framework, and then specifically address microservice implementation patterns. The source code repository for this LiveLesson is located at https://github.com/livelessons-spring/building-microservices.
